In the technical scheme of the disclosure, by the cleaning systems 150 be equivalent in above-mentioned robot 100 Improve, can obtain optimizing the wind path structure under structure, thus under identical dynamic condition, energy Enough reduce the windage loss in wind path structure, improve dust collection efficiency.Below in conjunction with embodiment, to the disclosure Technical scheme be described.

Fig. 5 is the cross section of the wind path structure according to a kind of automatic cleaning equipment shown in an exemplary embodiment Sectional view；Wherein, when the automatic cleaning equipment shown in Fig. 5 be robot 100 as Figure 1-4 or During other similar devices of person, the wind path structure of this automatic cleaning equipment can correspond to above-mentioned robot 100 Cleaning systems 150.For the ease of describing, Fig. 5 shows that automatic cleaning equipment is in an exemplary enforcement Directional information in example, including the direct of travel along y-axis (in which it is assumed that y-axis left direction is forward direction Driving direction, i.e. "+"；Y-axis right direction is backward driving direction, i.e. "-") and along z-axis Vertical direction.

As it is shown in figure 5, the wind path structure of automatic cleaning equipment may include that cleaning member 1, clean right As storage member 2, power part 3, one-level air channel 4 and light breeze road 5.Wherein, cleaning member 1, Cleaning object storage member 2 and power part 3 along automatic cleaning equipment direct of travel i.e. y direction successively Arrangement, and one-level air channel 4 is between cleaning member 1 and cleaning object storage member 2, light breeze road 5 between cleaning object storage member 2 and power part 3.So, the embodiment shown in Fig. 5 can To form following air channel: 4 → cleaning object storage member 2 → light breeze road, cleaning member 1 → one-level air channel 5 → power part 3 so that the wind that power part 3 produces can be realized by cleaning member by above-mentioned air channel 1 to the flowing of power part 3, and flow direction is illustrated by the direction of arrow in Fig. 5；Wherein, power The wind that parts 3 produce flows between cleaning member 1, one-level air channel 4 and cleaning object storage member 2 Time, can be delivered to clean object by cleaning objects such as dust that cleaning member 1 cleans, graininess rubbish In storage member 2, it is achieved clean operation.

Sweeping efficiency DPU is the accurate embodiment of the cleaning capacity of automatic cleaning equipment, by suction efficiency and rolling Brush sweeps both efficiency and together decides on, and suction efficiency discussed herein is main, and suction efficiency is dust removal ability Accurately embody, embody the efficiency converting electrical energy into mechanical energy, suction efficiency=suction power/input work Rate, input power is the electric energy of the input of blower motor, sucks power=air quantity * vacuum, input power After increasing to certain value, starting to produce the air quantity sucked, along with the increase of input power, air quantity constantly increases Adding, vacuum is gradually reduced, and sucking power is then first to increase to reduce afterwards, makes input power be operated in suction Enter in the scope that power is higher.

For same input power, air quantity and vacuum are all the biggest more can obtain high suction efficiency. The loss of vacuum reduces and depends on avoiding of leaking out, namely encapsulation process.The loss of air quantity reduces Depend on the smooth wind path structure without abrupt change, specifically include that from round brush lower end whether wind specifically Nondestructively entering air channel, wind blows to dirt box and enters during blower fan by wide-angle reflection from round brush lower end Number of times, duct cross-section amasss whether produce substantial amounts of turbulent flow etc. when changing.The overall structure of wind path sets Being counted as organic whole, the structural change of parts all can produce great variety to complete machine dust collection efficiency.

Because round brush is as cleaning member 1, its width the widest then single cleaning width is the widest, and dirt box is made For cleaning object storage member 2, parts are co-located in shell with road wheel etc. for it, and restricted width is not Can be the widest, and in order to increase vacuum fine pressure to be drawn into by rubbish in the middle of dirt box, the entrance of dirt box is the most not Can be the widest, between round brush and dirt box, therefore there is the first air channel, and cross section is the least；Going out of dirt box Mouthful by strainer filtering air, in order to avoid the blocking of filter screen, affect air channel unimpeded, and dirt box discharge area is logical The biggest, and blower fan is as power part 3, its entrance hole diameter then exports much smaller than dirt box, therefore dirt box And there is the second air channel between blower fan, and cross section is also the least.Although there is part automated cleaning at present Using such two air channels in the wind path of equipment, the Roomba series of such as iROBOT is swept the floor machine People, but and be provided without doing the wind path structure optimizing design for the two air channel.

Although it practice, wind path all can include round brush, dirt box, blower fan, two cross sections even can be there are The least air channel, but the difference of air channel shape makes suction efficiency far from each other.

Wind path in the disclosure makes the entrance air channel, round brush lower end of wind self-relocation, because floating round brush can be not Tightly can fit with ground in level region to be cleaned, wind loss is the least.Floating round brush Realize coming from the flexible material character in one-level air channel and the structure making round brush flexible up and down with topography variation sets Meter.

Round brush accommodates chamber through round brush and enters one-level air channel, and the shape in one-level air channel makes the fine pressure value of wind smooth Raise, rubbish is moved into obliquely dirt box；After the gradient in one-level air channel makes wind enter dirt box, Dirt box is left with big angle of reflection in dirt box top；The rubbish entering dirt box falls under gravity into dirt Cassette bottom portion, and the wind moved obliquely is blown out to export from filter screen after big angle of reflection by dirt box top, Enter light breeze road；Wherein, the purpose of design in light breeze road is to make the wind from filter screen blowout the fewest Loss ground enters blower fan mouth with certain orientation.

Below each structure in wind path is described in detail:

1, the structure in one-level air channel 4

In the technical scheme of the disclosure, by the guiding function in one-level air channel 4 so that power part 3 The dust etc. that cleaning member 1 cleans can be cleaned object and be delivered to clean object storage member by the wind produced In 2.

For overall structure, as it is shown in figure 5, one-level air channel 4 can be in bell mouth shape, and force one wind The sectional area that on road 4, arbitrary place is corresponding is anti-phase about the spacing distance between this arbitrary place and cleaning member 1； In other words, the relatively large side of " horn mouth " is right towards cleaning member 1, relatively small side towards cleaning As storage member 2.

In this embodiment, by the bell mouth shape being configured to gradually successively decrease by the sectional area in one-level air channel 4, The static pressure making corresponding position is incremented by therewith, i.e. forms increasing suction；So, when dust, The cleaning cleaned parts of object 1 such as rubbish sweep and band is to behind one-level air channel 4, along with cleaning object progressively Away from cleaning member 1, progressively near cleaning object storage member 2 (the most progressively near power part 3), Although the sweeping power that cleaning member 1 applies to cleaning object is gradually reduced, but owing to power part 3 is to clearly The suction that clean object applies is gradually increased such that it is able to guarantee to clean object be attracted and be delivered to clean right As in storage member 2.

Further, when cleaning member 1 is round brush assembly, as it is shown in figure 5, the entering of one-level air channel 4 Mouthful end is towards the round brush 11 of round brush assembly, and arrival end 41 is vertical with direct of travel in the horizontal plane Width on direction (i.e. x-axis direction) is incremented by from the top down.In order to make it easy to understand, for shown in Fig. 5 One-level air channel 4 and round brush 11 between matching relationship, Fig. 6 shows one-level air channel 4 and round brush 11 The perspective view cooperated.As shown in Figure 6, near the entrance of round brush 11 on one-level air channel 4 End 41 has larger sectional area, the port of export 42 away from round brush 11 has small cross sections and amasss.Wherein, base In above-mentioned " being incremented by " feature of arrival end 41, the cross section of this arrival end 41 can be trapezoidal, and narrower The second edge 412 be trapezoidal upper base, the first wider edge 411 be trapezoidal bottom；When So, as long as meeting above-mentioned " being incremented by " feature, the cross section of arrival end 41 can also use other shapes, than As used arc etc. corresponding to two waists of above-mentioned " trapezoidal ", this is not limited by the disclosure.

In this embodiment, by using trapezoidal or similar meeting at the arrival end 41 in one-level air channel 4 The shape of above-mentioned " being incremented by " feature so that the static pressure of corresponding position is incremented by therewith, then when dust, Rubbish etc. cleaning object swept by round brush 11 and band to arrival end 41 time, power part 3 produce wind energy Enough provide enough suction so that the cleaning object being swept to arrival end 41 can be inhaled into clearly as much as possible In clean object storage member 2, contribute to promoting cleaning efficiency.

As it is shown in figure 5, the arrival end 41 in one-level air channel 4 can be connected to the round brush as cleaning member 1 The round brush storehouse 12 of assembly, and by the opening on this round brush storehouse 12 towards round brush 11；Wherein, such as Fig. 7 Shown in, one-level air channel 4 includes two sidewalls on the rotating direction of round brush 11: after being positioned at direct of travel The first side wall 43 of side, being positioned at the second sidewall 44 of the front side of direct of travel, both can pass through following side Formula configures.

1) the first side wall 43

In one embodiment, the first side wall 43 can be along the tangent line side of the circular cross-sectional area in round brush storehouse 12 To setting.Than as it is shown in fig. 7, round brush storehouse 12 can include left side arcuate structure and right side L on cross section The some such as type structure, wherein the arch section in the arcuate structure of left side is corresponding to the circle shown in Fig. 7 Dashed region, thus this circular dashed line region corresponding to this arch section can be equivalent to above-mentioned circle and cut Region, face；Correspondingly, the first side wall 43 in one-level air channel 4 can be along the tangent line side in this circular dashed line region To setting, such as in the relative position relation shown in Fig. 7, owing to one-level air channel 4 is positioned at round brush assembly Oblique upper and on direct of travel, be partial to the rear of round brush 11, thus the first side wall 43 can be along vertically Direction is arranged.

In this embodiment, after round brush 11 sweeps cleaning object from ground, cleaning object is first along round brush Gap motion between 11 and round brush storehouse 12；And along with cleaning object by roller brushes structure to one-level air channel 4 Movement, by the first side wall 43 is arranged along above-mentioned tangential direction so that cleaning object movement locus Flowing with wind direction all will not be by the stop of the first side wall 43, it is ensured that cleaning object passes through force one wind Road 4 enters in cleaning object storage member 2.

2) the second sidewall 44

In one embodiment, in conjunction with Fig. 5 and Fig. 7, when cleaning member 1 is round brush assembly, and force one wind When the rear of round brush 1 is partial in road 4 on direct of travel, the arrival end 41 in one-level air channel 4 is towards traveling Round brush 11 at front side (left side in the such as Fig. 5) obliquely downward in direction, the port of export 42 are connected to row Enter the inlet air cleaning object storage member 2 at rear side (right side in the such as Fig. 5) oblique upper in direction Mouthfuls 21, and the air outlet 22 of cleaning object storage member 2 is positioned at non-top sides (i.e. air outlet 22 not position At top side 23, such as Fig. 5 is positioned at right side wall).

Wherein, second sidewall 44 in one-level air channel 4 towards the oblique rear-inclined of horizontal plane (i.e. as close possible to water Plane), even if also the second sidewall 44 forms the angle the biggest with z-axis vertical direction.It practice, Owing to the inner space of automatic cleaning equipment is limited, cause roller brushes structure, one-level air channel 4 and cleaning object Arranging between storage member 2 grade is extremely compact, and joint space-efficient mode is by complete for one-level air channel 4 Entirely arrange along z-axis, but that can lose air quantity significantly, thus be substantially reduced suction efficiency；And in the disclosure Embodiment in, under the conditions of limited inner space, by increasing between the first side wall 43 and z-axis Angle, can do wind direction and guide obliquely, after making wind enter the inside of cleaning object storage member 2, After the wide-angle reflection of inwall top side 23, by the filter screen (not indicating in figure) at air outlet 22 to connect The direction of nearly level is discharged, and the wind path design of a this wide-angle reflection is the least to the loss of air quantity.And In the related, when using, in order to save space, the wind path derived straight up by wind completely, due to Wind experience straight up turns the result of mouth and is reflected down, thus air quantity can led after upwards impact Lose in a large number at mouth to turning of level.On the other hand, wind is derived straight up by avoiding, can keep away Exempt from the moment shut down at automatic cleaning equipment, cause and drop out still in the cleaning object in one-level air channel 4 The external world, causes the secondary pollution to ground.

Further, due to one-level air channel 4 arrival end 41 towards the round brush 11 of lower left, the port of export 42 even It is connected to clean the air intake vent 21 of object storage member 2, thus one-level air channel 4 is by right to cleaning for wind guiding As storage member 2 internal time, wind and the cleaning object swept along thereof can be made directly to blow to clean object incorporating section The inwall top side 23 of part 2；And owing to wind is when directly blowing to top side 23, clean object storage member 2 Air outlet 22 not at this top side 23 at so that at top side 23 occur big angle of incidence anti- Penetrate, after conversion wind direction, entered light breeze road 5 by air outlet 22；After wind enters cleaning object storage member 2 Sectional area becomes big, causes the decline of wind speed, cleaning object to be fallen at top side 23 due to wind speed decreased, Thus reside in cleaning object storage member 2；Simultaneously as wind speed decreased and the change of wind direction, institute Although air outlet 22 can be blowed to wind self and enter light breeze road 5, but cannot continue cleaning right As blowing at air outlet 22, thus when cleaning object storage member 2 is at dirt case assembly and air outlet 22 When being provided with filter screen 24, can avoid cleaning object and directly be blown to filter screen 24 surface, it is right to prevent from cleaning As the surface of filter screen 24 is caused obstruction, contribute to promoting air quantity utilization rate.

Additionally, when cleaning object storage member 2 and being dirt case assembly, as shown in Figure 8, this dirt case assembly The sidewall 25 being provided with air intake vent 21 is detachable, and when this sidewall 25 is removed, can be formed and be used for inclining The pour spout 26 of the cleaning object of storage in the case assembly of falling dirt.Owing to air intake vent 21 is arranged on sidewall 25, Thus the specification of sidewall 25 is naturally larger than air intake vent 21, so after being dismantled by sidewall 25, rule can be formed Lattice are more than the pour spout 26 of air intake vent 21, it is simple to the cleanings such as user's dust to collecting in dirt box structure are right As toppling over.

2, the structure of cleaning member 1

As an exemplary embodiment, the cleaning member 1 in the automatic cleaning equipment of the disclosure can be rolling Brush assemblies.Fig. 9 shows the perspective view of the main brush module in round brush assembly, and Figure 10 is Fig. 9 The decomposition texture schematic diagram (visual angle in Figure 10 is for observing from bottom to top along z-axis) of shown main brush module； As shown in figs. 9-10, this main brush module can include round brush 11 and round brush storehouse 12, and round brush storehouse 12 enters one Step includes floating system support 121 and round brush lid 122.

1) round brush 11

Figure 11 shows the structural representation of round brush 11.As shown in figure 11, the round brush in this round brush assembly 11 can be glue hair mixing brush, is i.e. provided with glue brush part 112 and hair in the rotating shaft 111 of round brush 11 simultaneously Brush part 113, so can take into account the multiple cleaning ambient such as floor, woollen blanket.The adhesive tape of glue brush part 112, The direction of growth of the hairbrush of hairbrush part 113 is basically identical with the radial direction of rotating shaft 111, and glue brush part 112 Adhesive tape width, hairbrush part 113 hairbrush width basically identical with the width of the arrival end 41 in one-level air channel 4； Wherein, the micro-row being bent upwards in centre shown in Figure 11 be a glue brush part 112, in undaform one Row is a hairbrush part 113, and each round brush 11 can include at least one glue brush part 112 and at least one Individual hairbrush part 113.

Glue brush part 112 is not taked with hairbrush part 113 parallel or connects subparallel set-up mode, but two There is bigger angle, to guarantee that glue brush part 112 and hairbrush part 113 can each realize self between person Application function.

(1) glue brush part 112

Owing to there is bigger gap between brush tuft 113A on hairbrush part 113 so that wind be easy to from Running off between gap, the help to forming vacuum environment formation is smaller.Therefore, by arranging glue brush part 112, effect of going for a drive can be formed, and when intensity of going for a drive reaches preset strength, it is right to assist to realize The sweeping of cleaning object so that cleaning object can be more convenient under the blowing of the sweeping of round brush 11 and wind Be transported to clean in object storage member 2.

Wherein, the glue brush part 112 setting direction in the face of cylinder of round brush 11 and the side of setting of rotating shaft 111 More hour, glue brush part 112 is completely along the setting of rotating shaft 111 the most in the limiting case for angle between to Direction carries out straight line arrangement, when the x-axis along embodiment illustrated in fig. 11 is arranged i.e. completely, and glue brush part 112 Maximum can be formed go for a drive intensity.

And on the basis of in view of intensity of going for a drive not less than above-mentioned preset strength, the disclosure is further Combine considering of other factors.Than in embodiment as shown in figure 11, glue brush part 112 is the most not Arrange fully according to straight line, and arrange along the mode close to straight line in being utilized in the face of cylinder of round brush 11 Cloth, and make the centre position rotating direction end bend to round brush 11 of glue brush part 112, so that power The wind that parts 3 produce converges in glue brush part 112 and forms the centre position of bending, thus can enter one Walk and cleaning object is collected.And on the other hand, the glue brush part 112 of complete lineal layout can only obtain The maximum of moment is gone for a drive effect, arranging of certain angle of bend can be by the round brush 11 in rolling process Effect of going for a drive keep a period of time.

It practice, as shown in Figure 10, by being pointed to one-level air channel 4 and the rolling of oblique upper, round brush storehouse 12 Brush 11 carries out contrast and understands: on width (or left and right directions), the specification in one-level air channel 4 is less than Round brush 11；Wherein, limited air quantity can be utilized to realize bigger static pressure compared with the one-level air channel 4 of small dimension Value, it is simple to being delivered to cleaning object clean object storage member 2, the round brush 11 of bigger specification then may be used To realize bigger cleaning area, so above-mentioned size heterogeneity is actually in the lifting to cleaning efficiency And the design means taked.So, by the shape of glue brush part 112 is carried out reasonable disposition so that wind Collect to the centre position of glue brush part 112, above-mentioned size heterogeneity can be matched with, it is ensured that will be all The cleaning object swept by round brush 11 all sends into one-level air channel 4, and is delivered to further clean object storage In parts 2.

It addition, in Figure 10 it can be seen that floating system support 121 have at air intake (lower end in figure) to The wind path in one-level air channel 4 guides arc structure 1211, and this arc structure 1211 and one-level air channel 4 Arc shape 40 is that curvature is consistent, thus this arc structure 1211 improves wind and enters the efficiency in air channel, Decrease wind loss.

(2) hairbrush part 113

In embodiment of the disclosure, hairbrush part 113 is in the face of cylinder of round brush 11 and between rotor shaft direction Form relatively large deviation angle；For each hairbrush part 113, by forming above-mentioned relatively large deviation angle, can Make some brush tuft 113A of this hairbrush part 113 of composition along rotor shaft direction arrange successively time, in the circumferential Realize the bigger angle of coverage to round brush 11, such as the circumferential angle of coverage of round brush 11 is reached preset angle Degree.

On the one hand, by expanding the circumferential angle of coverage to round brush 11, cleannes and cleaning effect can be promoted Rate.Round brush 11 is in rolling process, it is possible to achieve the cleaning to bottom surface；And when hairbrush part 113 is to round brush When the circumferential angle of coverage of 11 reaches 360 °, can guarantee that round brush 11 all the time can in rolling process Realize cleaning operation.

Meanwhile, by increasing the angle of deviation between hairbrush part 113 and rotor shaft direction, so that each hair The circumferential angle of coverage of round brush 11 is increased by brush part 113 therewith, thus covers in the circumference realizing formed objects During lid angle, the quantity of required hairbrush part 113 is less.For example, it is assumed that need to realize round brush 360 ° of circumferential angle of coverage of 11, if the circumferential angle of coverage of each hairbrush part 113 is 60 °, then Need 6 hairbrush parts 113, and if time the circumferential angle of coverage of each hairbrush part 113 is 120 °, then Only need 3 hairbrush parts 113.Therefore, by increasing the deviation between hairbrush part 113 and rotor shaft direction Angle, it is possible to reduce hairbrush part 113 is arranged quantity, contributes in the case of guaranteeing cleaning effect, Reduce the production cost of round brush 11.

On the other hand, hairbrush part 113 needs contact ground to clean during cleaning；Wherein, by In the flexible nature of hairbrush part 113, certain deformation will be produced in cleaning process, formed to whole from " support " effect of dynamic cleaning equipment.So, if the hairbrush part 113 circumferential cone of coverage to round brush 11 When degree is not enough, form difference in height by resulting between circumference covering and the region not forming circumference covering, Cause automatic cleaning equipment jolting or shaking in the z-axis direction, affect the execution of clean operation；Therefore, When hairbrush part 113 is capable of 360 ° of circumferential angle of coverage, can be jolted by elimination, shake, Thus can either guarantee that automatic cleaning equipment maintains continual and steady output, and automated cleaning can be reduced The noise that equipment produces, it is also possible to avoid impacting motor, contributes to extending automatic cleaning equipment Service life.

2) round brush lid 122

In the technical scheme of the disclosure, when cleaning member 1 is round brush assembly, Figure 12 shows this rolling The perspective view of the round brush lid 122 in brush assemblies, this round brush lid 122 can include antiwind protecting Keep off 1221 and on direct of travel, be positioned at the flexible glue scraping article 1222 at this antiwind bib 1221 rear.Anti-tangle Can stop that the cleaning object of large volume enters air channel and forms blocking, on the other hand around bib 1,221 1 aspect Stop that the slender bodies such as electric wire enter round brush storehouse 12 and produce winding.

Understanding in conjunction with Fig. 9, round brush lid 122 is positioned at below round brush 11 in the z-axis direction, can stop rule The excessive cleaning object of lattice is involved in round brush component internal, affects normal clean operation.And flexible glue scraping article 1222 lower sections being positioned at antiwind bib 1221 in z-axis, and flexible glue scraping article 1222 is positioned on the y axis The direct of travel end of round brush 11, between this flexible glue scraping article 1222 and round brush 11 keep certain distance (as 1.5-3mm), and by fitting in ground so that it is sub-fraction directly can not rolled by round brush 11 Cleaning object intercept and scooped up, so that it is involved in round brush under the sweeping of round brush 11 and the blowing of wind Between 11 and round brush storehouse 12, hence into one-level air channel 4.The position of flexible glue scraping article 1222 and angle Select to make to clean object and be always positioned at optimal cleaning and suction position, it is to avoid in flexible glue adhesive tape 1222 Leave over.

As shown in figure 12, the antiwind bib 1221 end on direct of travel (can be the y of Figure 12 Axle negative direction, the right-hand member of the most antiwind bib 1221) traveling being matched with automatic cleaning equipment can be provided with Obstacle detouring aid 1221A in direction, on the one hand this obstacle detouring aid 1221A can assist automated cleaning to set The standby obstacle detouring (i.e. surmounting obstacles) that plays acts on, and on the other hand this obstacle detouring aid 1221A can be butted on soft The upper surface of glue scraping article 1222, makes the bottom margin of this flexible glue scraping article 1222 be at automatic cleaning equipment Surface to be cleaned (such as ground, desktop etc.) can be fitted in during duty all the time, and avoid this flexible glue to scrape Bar 1222 is rolled-up because of barriers such as the rubbish in surface to be cleaned, affects follow-up cleaning effect.

In one embodiment, obstacle detouring aid 1221A can be that antiwind bib 1221 is at direct of travel On the projection that formed of end downwards (i.e. z-axis negative direction shows as " top " in Figure 12).Figure 13 is the close-up schematic view of the matching relationship between obstacle detouring aid 1221A and flexible glue scraping article 1222； As shown in figure 13, the projection as obstacle detouring aid 1221A may include that and is positioned on front side of direct of travel First composition limit AA, when this first composition limit AA tilt on rear side of direct of travel time, such as Figure 13 In this first composition limit AA when tilting from left to right, owing to automatic cleaning equipment advances from right to left Drive, thus when there is barrier 6 in surface to be cleaned, this first composition limit AA and above-mentioned suspension System frame 121 matches, and can cross this obstacle by smooth guide automatic cleaning equipment during obstacle detouring Thing 6, without being stuck.

As shown in figure 13, the projection as obstacle detouring aid 1221A may include that and is positioned at direct of travel Second composition limit BB of rear side, and second formed limit BB by this and be butted on the upper surface of flexible glue scraping article 1222； So, when projection by first form limit AA and second form limit BB constitute time, this projection can be figure Tip-angled shape shown in 13.

It should be understood that use obstacle detouring aid 1221A of convex form, its minimum point should not be low In the minimum end face of round brush lid 122, thus in the walking process of automatic cleaning equipment, it is to avoid with by clearly Face cleaning is formed and scratches and produce extra resistance, contributes to promoting the cleaning efficiency of automatic cleaning equipment.

3) floating system support 121

As shown in figure 14, floating system support 121 may include that fixed support 1212 and floating bracket 1213 etc., and on this floating system support 121, it is also equipped with one-level air channel 4 and round brush motor 1214 Deng.Two the installing hole 1212A being provided with on left and right directions on fixed support 1212, and floating bracket 1213 two the installation axle 1213A being provided with on left and right directions, then by each installation axle 1213A and phase Answering spacing between installing hole 1212A and be rotatably assorted, this floating bracket 1213 can realize vertically " floating " on direction.

Therefore, when automatic cleaning equipment is in normal cleaning process, floating bracket 1213 is at gravity shadow Extreme lower position is turned to, no matter on floor, carpet or other rough cleaning surfaces, in rolling under sound In the floating path domain of brush 11, the round brush 11 installed in this floating system support 121 can be close to In surface to be cleaned, to clean with realizing the patch of peak efficiency, dissimilar cleaning surface all has preferably Patch ground effect, the sealing in air channel is contributed substantially.

And when there is barrier 6 in surface to be cleaned, by upper and lower " floating " of floating bracket 1213, The interaction between round brush 11 grade and barrier 6 can be reduced, thus assist automatic cleaning equipment light Realize obstacle detouring.Wherein, one-level air channel 4 between fixed support 1212 and floating bracket 1213, because of And the round brush 11 floated proposes flexible demand to one-level air channel 4, because the air channel of rigidity cannot absorb rolling The floating change of brush 11, this demand is realized by the flexible material in one-level air channel 4；So, when one-level air channel When the 4 employings such as flexible materials such as flexible glue are made, can be squeezed by floating bracket 1213 during obstacle detouring Press one-level air channel 4 to make it produce deformation, thus realize smoothly upwards " floating ".

Additionally, in normal cleaning process, for the surface to be cleaned of the rough surfaces such as carpet, by floating " floating " effect of dynamic support 1213, it is possible to reduce interfering between round brush 11 grade and carpet, Thus reduce the resistance that round brush motor 1214 is subject to, contribute to reducing the power consumption of round brush motor 1214, and Extend its service life.

3, the smooth guide in light breeze road 5

Figure 15 is the top view that wind path structure shown in Fig. 5 is corresponding.As shown in figure 15, cleaning member 1, Cleaning object storage member 2 and power part 3 are in direct of travel (the i.e. y-axis side along automatic cleaning equipment To) be arranged in order while, cleaning object storage member 2 is with power part 3 also in x-axis direction (i.e. The left and right directions of automatic cleaning equipment) on deviate from each other, thus wind from cleaning object storage member 2 blow to During power part 3, the motion existing along the y-axis direction simultaneously and going up along the x-axis direction, i.e. wind are flowing over There is " turning " in journey.Cleaning object storage member 2 and power part 3 also can in the direction of the x axis without Deviating from each other, this is not limited by the disclosure.

As shown in figure 15, light breeze road 5 in bell mouth shape (near cleaning object storage member 2 side Sectional area is relatively large, relatively small near the side sectional area of power part 3) so that wind is gathered Air inlet to power part 3.Wind from cleaning object storage member 2 be blown into light breeze road 5 time, due to The reduction of sectional area, wind is the inwall of the windward side 51 directly blowing to light breeze road 5；So, in these public affairs In the technical scheme opened, by the inwall windward side in this light breeze road 5 being configured to arc, on the one hand can In the direction of the x axis the wind of cleaning object storage member 2 output is guided so that it is be blown to power The air inlet of parts 3, on the other hand can be matched with the flowing of wind, it is to avoid it is caused stop or interference Produce turbulent flow, thus contribute to reducing windage loss, improving air quantity utilization rate.

, understand in conjunction with Fig. 5 Yu Figure 15 meanwhile, after cleaning object cleaned parts 1 clean, pass through power The wind (and the respective outer side edges in one-level air channel 4) that parts 3 produce is transported to clean object storage member In 2, thereby through promoting the air quantity utilization rate of wind path structure, reducing windage loss, wind pair can be increased The conveying intensity of cleaning object, thus promote cleannes and the cleaning efficiency of automatic cleaning equipment.

4, power part 3 is inclined

Figure 16 is that the cross section according to a kind of light breeze road shown in an exemplary embodiment with power part is cutd open View.As shown in figure 16, light breeze road 5 is away from cleaning object storage member 2 (not shown in Figure 16) End form air outlet 52, and this air outlet 52 is also snap-fit attachment to the air inlet 31 of power part 3. Wherein, plane residing for air outlet 52 intersects with horizontal plane, i.e. air outlet 52 favours horizontal plane；So, When power part 3 is axial flow blower, and the rotating shaft of air inlet 31 and this axial flow blower (rotor shaft direction can be joined See in Figure 16 indicate chain-dotted line direction) in the same direction time, effectively appear this axial flow blower and favour level Face is placed.

When plane residing for air outlet 52 and air inlet 31 is perpendicular to horizontal plane, wind is in light breeze road 5 During flowing and entered power part 3 by light breeze road 5 in portion, it is essentially all in horizontal plane Realize flowing, thus when wind is blown into axial flow blower by light breeze road 5, wind direction is arranged essentially parallel to rotating shaft side To, thus can make to realize maximum conversion efficiency as the axial flow blower of power part 3 (such as by electric energy Be converted to the efficiency of wind energy)；And when plane residing for air outlet 52 and air inlet 31 is parallel to horizontal plane, Wind flows inside light breeze road 5 the most along the horizontal plane, but when being entered power part 3 by light breeze road 5, Need then vertically flow so that the conversion efficiency as the axial flow blower of power part 3 is minimum.

But, owing to the inner space of automated cleaning parts is extremely limited, it is impossible to realize air outlet 52 and enter Plane residing for air port 31 is perpendicular to horizontal plane, so in the technical scheme of the disclosure, by increasing as far as possible As the angle between axial flow blower and the horizontal plane of power part 3, on the one hand can be to automated cleaning portion The inner space of part carries out Appropriate application, on the other hand can make the conversion efficiency of axial flow blower Bigization.

In the technical scheme of the disclosure, for wind flow process in light breeze road 5, it is also possible to make Towards the sidewall outwardly convex at air outlet 52 on light breeze road 5, to increase light breeze road 5 at air outlet Inner chamber capacity at 52, makes wind that power part 3 the produces energy loss at air outlet 52 less than pre- If loss.Such as Figure 17 is the right view that wind path structure shown in Figure 11 is corresponding, as shown in figure 17, when going out When air port 52 is positioned at the top side in light breeze road 5, it is bottom side towards the sidewall at air outlet 52, thus can To be formed down the bulge-structure 53 shown in Figure 17, thus increase light breeze road 5 at air outlet 52 Inner chamber capacity so that wind changes wind direction (in plane residing for air outlet 52 non-perpendicular at air outlet 52 In the case of horizontal plane) and in the case of being blown into power part 3, it is provided that bigger cushion space, with Reduce wind energy loss at air outlet 52.

5, complete machine air channel is hermetically sealed

Knowable to analysis above, vacuum and air quantity have significant contribution similarly for high suction efficiency. In the technical scheme of the disclosure, is all entered at all gaps that each parts junction in wind path structure is existed Row encapsulation process, such as fills flexible glue etc. at gap, thus avoids leaking out, namely reduce vacuum Loss.On the other hand, as shown in figure 15, at the air outlet of blower fan, flexible glue part 32 is used, wind is complete Main frame is derived in portion, and the use of flexible glue part 32 is leaked out in addition to (i.e. reducing vacuum) except can avoid, and also may be used To avoid dust to enter internal motor of automatic cleaning equipment etc., contribute to prolongation automatic cleaning equipment Service life.
